The present invention relates to the field of communications, and in particular, to a method, a terminal device, and a network device for transmitting an uplink channel/signal.

Background

In a New Radio (NR) system, transmission and reception of channels/signals of terminal devices have spatial characteristics. The network side configures spatial relationship information between channels/signals for the terminal device to indicate spatial relationship information between an uplink physical uplink control Channel (Physical Uplink Control Channel, PUCCH) or a sounding signal (Sounding Reference Signal, SRS) and a reference signal, wherein the reference signal may be a synchronization signal (Synchronization Signal, SSB)/physical broadcast Channel (Physical Broadcast Channel, PBCH) block, a Channel-state information reference signal (Channel-State Information Reference Signal, CSI-RS) or a sounding signal (Sounding Reference Signal, SRS).

In the NR, SSB is identified by an SSB Index (Index) in spatial relationship information between an uplink channel/signal and a reference signal configured on the network side, and the SSB-Index may identify the location of the SSB or may represent a Quasi Co-located (QCL) relationship of the SSB.

Several concepts are described in detail below.

1. NR-U system

Unlicensed spectrum is a nationally and regionally divided spectrum that can be used for radio communications and is generally considered to be a shared spectrum, i.e., communication devices in different communication systems can use the spectrum as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government. In order for individual communication systems using unlicensed spectrum for wireless communication to co-exist friendly over the spectrum, some countries or regions have stipulated regulatory requirements that must be met using unlicensed spectrum. For example, in the european region, the communication device follows the principle of listen-before-talk (LBT), that is, the communication device needs to perform channel interception before performing signal transmission on a channel of the unlicensed spectrum, and only when the channel interception result is that the channel is idle, the communication device can perform signal transmission; if the channel listening result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device is unable to signal. And in order to ensure fairness, in one transmission, the communication device cannot use the unlicensed spectrum channel for signal transmission for a period exceeding the maximum channel occupation time (Maximum Channel Occupation Time, MCOT).

2. Synchronization signal (Synchronization Signal, SS)/physical broadcast channel (Physical Broadcast Channel, PBCH) block (block) in an NR system

Common channels and signals in NR systems, such as synchronization signals and broadcast channels, need to cover the entire cell by means of multi-beam scanning to facilitate reception by UEs within the cell. The multi-beam transmission of the synchronization signal is achieved by defining SS/PBCH pulse set (burst set). One SS burst set contains one or more SS/PBCH blocks. One SS/PBCH block is used to carry the synchronization signal and broadcast channel of one beam. Thus, one SS/PBCH burst set may contain synchronization signals for SS/PBCH block number (number) beams within the cell. The maximum number of SSs/PBCH block number can be expressed as L, which is related to the frequency band of the system, e.g., the frequency range is less than or equal to 3GHz, L being 4; the frequency range is 3GHz to 6GHz, L is 8; the frequency range is 6GHz to 52.6GHz, L is 64.

Fig. 2 shows a schematic diagram of time-frequency resources occupied by an SS/PBCH block (hereinafter referred to as "SSB"). As shown in fig. 2, an SSB may include a primary synchronization signal (Primary Synchronization Signal, PSS) of an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol, and may further include a secondary synchronization signal (Secondary Synchronization Signal, SSS) of an OFDM symbol and NR-PBCH of two OFDM symbols, where a time-frequency resource occupied by the PBCH may include a demodulation reference signal (Demodulation Reference Signal, DMRS) used for demodulation of the PBCH.

All SS/PBCH blocks within SS/PBCH burst set are transmitted within a time window of 5ms and are repeated with a period that may be configured by high-level parameter SSB time (SSB-timing) information, e.g., the period may include 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc. For UE, the index (index) of the SSB is obtained through the received SS/PBCH block, the SSB index corresponds to the relative position of the SSB in a 5ms time window, and the UE obtains frame synchronization according to the information and the field indication information carried in the PBCH. The index of the SS/PBCH block may be indicated by DMRS of the PBCH or information carried by the PBCH.

Fig. 3 shows a slot distribution pattern of SSBs at different subcarrier spacings (subcarrier spacing, SCS) in an embodiment of the application. Taking a 15kHz subcarrier spacing, l=4 as an example, one slot (slot) contains 14 symbols (symbols) and can carry two SS/PBCH blocks, and 4 SS/PBCH blocks are distributed in the first two slots in the 5ms time window.

It should be understood that, in the embodiment of the present application, the number L of SSBs is the maximum number of SSBs, that is, the number of SSBs actually transmitted may be less than or equal to L. In the NR system, L is the maximum number of SSB transmitted in a certain frequency band, and the value range of SSB index is [0, L-1]. SSB index may be used for frame synchronization, and on the other hand, may also be used for UE to obtain QCL relation of SSB. The index of SS/PBCH block received at different times is the same, and it is considered that they have a QCL relationship.

When two reference signals (e.g., SSBs) have a QCL relationship, the large scale parameters of the two reference signals may be considered to be inferred from each other or may be considered to be similar, where the large scale parameters may include, for example, doppler delay, average delay, and spatial reception parameters. The UE may filter SSBs with QCL relationships during measurement as a measurement result of beam level.

3. Discovery reference signals (Discovery reference signal, DRS) in NR-U systems

In an NR-U system, for a Primary Cell (Pcell), a network device may send DRS signals for access and measurement, where the DRS may include at least SSB. In view of uncertainty in acquisition of channel usage rights on unlicensed spectrum, a network device may not successfully transmit SSB at a predetermined time due to possibility of LBT failure during transmission of SSB. Thus, NR-U defines a candidate location for SSB. For example, in a time window of up to 5ms, 20 candidate positions are defined for a subcarrier spacing of 30kHz for SSB and 10 candidate positions are defined for a subcarrier spacing of 15kHz for SSB. The maximum number of the transmitted SSBs is Q, and the base station determines to transmit the DRS using Q candidate positions among the plurality of candidate positions according to the detection result of the LBT within the DRS transmission window. The parameter Q may be configured by the network device for the terminal device, or may be specified by a protocol, which is not limited in this embodiment.

Fig. 4 shows a schematic diagram of LBT at candidate locations. As shown in fig. 4, here, taking a subcarrier spacing of 30kHz as an example, 20 candidate positions are defined, the maximum number Q of SSBs to be transmitted is taken as 8, and the possible starting positions of the 8 SSBs may be any one of the 20 candidate positions in fig. 4. It is assumed here that the base station performs LBT only at

candidate location indices

1, 4, 8 and 16 as shown in fig. 4, i.e. takes these four locations as possible starting locations for 8 SSBs. As shown in fig. 4, assuming that LBT performed by the base station before candidate position 12 is successful, SSB QCL index0-7 is correspondingly started to be transmitted.

Wherein the SSB QCL index in NR-U is of a different meaning than the SSB index in NR. In NR, SSB index can be used to obtain synchronization and QCL relationships, while in NR-U, synchronization is obtained through SSB position index, and QCL relationships are obtained through SSB QCL index.

As shown in fig. 4, the actual transmission position of the SSB may be any one or more of 20 candidate positions according to the time when the LBT is successful. For the transmission scheme of SSBs defined in NR-U, since the UE needs to obtain frame synchronization by SSBs received at candidate transmission positions, SSB position index needs to be defined for the candidate transmission positions. For example, taking the maximum number of SSBs transmitted q=8 and the number of candidate positions y=20 as an example, since the maximum number of SSBs of 8 may be transmitted in 20 candidate positions, SSB-carried SSB needs to be extended to 0 to 19 in order for the UE to obtain the position of the received SSB, and further obtain frame synchronization. And because the maximum number of SSBs sent is 8, the value range of SSB QCL index for obtaining the QCL relationship between SSBs is 0 to 7, that is, SSB position index is different from the value range of SSB QCL index. For SSBs transmitted at different times, if their SSB QCL indices are the same, then they are considered to have a QCL relationship. In other words, there is no QCL relationship between SSBs that are SSB QCL index-different. Wherein SSB QCL index=mod (Q), and the value of SSB QCL index ranges from 0 to Q-1.

FIG. 5 shows quasi co-location relationships of SSBs with different location indices. As shown in fig. 5, assuming that there are 20 candidate locations for transmitting SSBs, the range of values of the location indexes is 0-19, and the maximum number of SSB transmissions is 8, that is, the range of values of SSB QCL index for obtaining the QCL relationship between SSBs is 0 to 7, there may be a plurality of SSBs having different location indexes but having the QCL relationship. For example, as shown in fig. 5, three SSBs of

ssbpositiondex

0,8,16 each have a QCL relationship.

4. Spatial relationship information between channels/signals

In the NR system, transmission and reception of channels/signals of UEs have spatial characteristics. The network side configures spatial relationship information between channels/signals for the UE to indicate spatial relationship information between an uplink physical uplink control Channel (Physical Uplink Control Channel, PUCCH) or a sounding signal (Sounding Reference Signal, SRS) and a reference signal, where the reference signal may be an SSB, a Channel-state information reference signal (CSI-State Information Reference Signal), or an SRS. For example, when the network side indicates that there is a spatial relationship between the PUCCH and the SSB, the UE may transmit the PUCCH using the same spatial domain filter as that used to receive the SSB. For another example, when the network side indicates that there is a spatial relationship between the target SRS and the SSB, the UE will transmit the target SRS using the same spatial domain filter as receiving the SSB.

In NR, SSB is identified through SSB-Index in spatial relation information of uplink channel/signal and reference signal configured by network side; the SSB-Index has a value ranging from 0 to L-1, is carried in SSB, and SSB with different SSB-indices does not have QCL relationship, and can directly obtain the QCL relationship of the SSB through the SSB-Index.

In NR-U, SSB position index is carried in SSB, and QCL relations are obtained by SSB QCL index, which is not directly carried in SSB, but calculated by SSB position index and parameter Q. Thus, in NR-U, how to identify SSB is a problem that needs to be solved at present if SSB has a spatial relationship with uplink channel/signal. The embodiment of the application provides a method for transmitting an uplink channel/signal, which can solve the problem.

Fig. 6 is a schematic flow chart of a method 200 for transmitting an uplink channel/signal according to an embodiment of the present application. As shown in fig. 6, the method 200 includes: s210, sending the spatial relationship indication information. Specifically, the network device sends spatial relationship indication information to the terminal device, where the spatial relationship indication information indicates a reference signal having a spatial relationship with the uplink channel/signal.

It should be appreciated that the method 200 of embodiments of the present application may be used for unlicensed spectrum, for example, the method may be applied in NR-U systems, but embodiments of the present application are not limited thereto. In addition, the method 200 may be performed by a terminal device and a network device, for example, the terminal device may be a terminal device as shown in fig. 1; the network device may be a network device as shown in fig. 1.

Optionally, the uplink channel/signal in the embodiment of the present application may include PUCCH and/or SRS.

Optionally, the reference signal indicated by the spatial relationship indication information in the embodiment of the present application may include at least one of the following: SSB, CSI-RS, and SRS. In the embodiment of the application, SSB is SS/PBCH block.

It should be understood that, in the embodiment of the present application, the reference signal is taken as an SSB for example, that is, the spatial relationship indication information sent by the network device indicates an SSB that has a spatial relationship with the uplink channel/signal, and for distinguishing, the SSB is referred to herein as a target SSB, and the target SSB may refer to any SSB.

Specifically, the spatial relationship indication information is used for indicating the target SSB, so that the terminal device determines the target SSB according to the spatial relationship indication information. Wherein the spatial relationship indication information may include location information of the target SSB, for example, the location information of the target SSB may include a location index of the target SSB; alternatively, the spatial relationship indication information may include quasi co-location (QCL) information of the target SSB, for example, the QCL information of the target SSB may include a QCL index of the target SSB.

Alternatively, as an embodiment, for the case that the spatial relationship indication information includes the location information of the target SSB, for example, the location information of the target SSB may include a location index (location index) of the target SSB, where the location index of the target SSB is used to indicate an index of a transmission location of the target SSB, the terminal device determines the corresponding target SSB according to the location index of the target SSB in the spatial relationship indication information.

Wherein the range of the position index of the target SSB indicates the possible transmission position of the target SSB. For example, the range of values of the position index of the target SSB may be related to the transmission window size of the DRS that includes the target SSB; and/or the value range of the position index of the target SSB may also be related to the subcarrier spacing.

For example, taking fig. 4 as an example, the DRS window size is 5ms, the subcarrier spacing of the SSB is 30kHz, and the number of possible transmission positions of the SSB is 20, that is, the position index of the target SSB has a value ranging from 0 to 19. For another example, if the DRS window size is 5ms and the subcarrier spacing of the SSB is 15kHz, 10 candidate positions are defined, that is, the number of possible transmission positions of the SSB is 10, that is, the position index of the target SSB has a value ranging from 0 to 9. The network device may select one or more of the above 20 or 10 possible transmission locations, for example, by using the LBT method, so as to transmit one or more target SSBs, and the position index of the target SSB included in the spatial relationship indication information may represent an index of a location where the target SSB is actually transmitted, so that the terminal device may determine the location index of the target SSB and may also receive the target SSB.

Alternatively, as another embodiment, for the case that the spatial relationship indicating information is QCL information of the target SSB, for example, the QCL information of the target SSB may include a QCL index (QCL index) of the target SSB, and the QCL information of the target SSB or the QCL index of the target SSB may be used to represent a QCL relationship between the target SSB and other SSBs, for example, a plurality of SSBs having a QCL relationship have the same QCL index, and conversely, SSBs having different QCL indexes do not have a QCL relationship therebetween.

The value range of QCL index of the target SSB is related to the maximum number Q of SSBs that are sent in one DRS transmission window and do not have QCL relation, for example, the value range of QCL index of the target SSB is 0 to Q-1.

As shown in fig. 6, the method 200 may further include: s220, SSBs having spatial relationships with the uplink channels/signals are determined. Specifically, the terminal device determines, according to the spatial relationship indication information, a target SSB having a spatial relationship with the uplink channel/signal, and determines target spatial relationship information corresponding to the target SSB.

Alternatively, as an embodiment, if the spatial relationship indication information includes the location information of the target SSB, for example, the location information of the target SSB may include a location index of the target SSB, the terminal device may determine the target spatial relationship information corresponding to the location index of the target SSB according to the location index of the target SSB.

It should be appreciated that for the location index of the target SSB, there is a location index of at least one SSB that is different from the location index of the target SSB, but the target SSB corresponds to the same spatial relationship information as the at least one SSB, the target SSB has a QCL relationship with the at least one SSB, that is, the at least one SSB having a QCL relationship with the target SSB also corresponds to the target spatial relationship information.

For example, the terminal device may determine, according to the correspondence between the position index of the SSB and the spatial relationship information, the spatial relationship information corresponding to the position index of the target SSB as the target spatial relationship information. In the correspondence between the position indexes of the SSBs and the spatial relationship information, the position indexes of the SSBs having the QCL relationship correspond to the same spatial relationship information, that is, the position indexes of the SSBs having the QCL relationship may be different, but the SSBs correspond to the same spatial relationship information.

For another example, the terminal device may further determine QCL information of the target SSB according to the location index of the target SSB, and determine spatial relationship information corresponding to the QCL information of the target SSB as target spatial relationship information, for example, the terminal device may determine, according to a correspondence between QCL information of the SSB and the spatial relationship information, that the spatial relationship information corresponding to the QCL information of the target SSB is target spatial relationship information.

It should be appreciated that the location index of the SSB may be used to determine a quasi co-sited index of the SSB. Taking the target SSB as an example, the relation between the position index of the target SSB and the QCL index of the target SSB is related to the parameter Q, that is, the SSB QCL index is calculated according to SSB position index. Specifically, the terminal device may determine the quasi co-sited index of the target SSB according to the following formula (1):

QCL＝mod(P，Q) (1)

wherein QCL is a quasi co-sited index of the target SSB, P is a location index of the target SSB, Q is a parameter for determining the quasi co-sited index of the target SSB, and for example, the Q may represent a maximum number of SSBs having no quasi co-sited relationship sent in a transmission window of one DRS. Alternatively, the parameter Q may be configured by the network device for the terminal device, or may be specified by a protocol, which is not limited thereto.

As can be seen from equation (1), for different SSB position index, there may be a plurality of SSBs corresponding to different SSB position index having the same QCL quasi co-sited index, that is, a plurality of SSBs corresponding to different SSB position index having QCL relationships with each other. For example, the entire range of values of SSB position index can be considered as a set, which can be divided into a plurality of subsets, the position index of SSBs contained in the same subset being different but having QCL relationships, i.e., SSBs within the same subset having the same QCL information; whereas the position index of SSBs belonging to different subsets are different and do not have QCL relation with each other, i.e. the QCL information of SSBs of different subsets is different.

Alternatively, in another embodiment, if the spatial relationship indication information includes QCL information of the target SSB, for example, the QCL information of the target SSB may include a QCL index of the target SSB, the terminal device may determine the target spatial relationship information corresponding to the QCL index of the target SSB according to the QCL index of the target SSB.

It should be appreciated that for QCL information of the target SSB, for example, taking the QCL index as an example, multiple SSBs of the same QCL index have QCL relationships, while multiple SSBs of different QCL indices do not have QCL relationships. In addition, the location indices of the SSBs having the same QCL index may be the same or may be different, i.e., there may be at least one SSB having a location index different from that of the target SSB, but the target SSB has a QCL relationship with the at least one SSB and the same QCL information. Also, SSBs having the same QCL index correspond to the same spatial relationship information, that is, at least one SSB having a QCL relationship with the target SSB also corresponds to the target spatial relationship information.

For example, the terminal device may determine, according to the correspondence between QCL information of the SSB and spatial relationship information, spatial relationship information corresponding to the QCL information of the target SSB as target spatial relationship information. In the correspondence between the QCL information and the spatial relationship information of the SSB, SSBs having the same QCL information have a QCL relationship, and SSBs having a QCL relationship correspond to the same spatial relationship information.

For another example, the terminal device may further determine a correspondence between QCL information of the SSB and spatial relationship information according to a correspondence between the position index of the SSB and the spatial relationship information; the terminal device may determine, according to the correspondence between QCL information of the SSB and the spatial relationship information, that the spatial relationship information corresponding to the QCL information of the target SSB is the target spatial relationship information. In the correspondence between the position indexes of the SSBs and the spatial relationship information, there are the plurality of SSBs having QCL relationships whose position indexes correspond to the same spatial relationship information, that is, the plurality of SSBs having QCL relationships whose position indexes may be different, but the plurality of SSBs whose position indexes correspond to the same QCL information and also correspond to the same spatial relationship information.

It should be appreciated that the location index of the SSB may be used to determine the QCL index of the SSB. For example, according to the above embodiment, according to the above formula (1), the QCL index corresponding to the position index of any one SSB can be determined, and for brevity, the description is omitted here.

Specifically, the terminal device receives the spatial relationship indication information, determines a target SSB according to the spatial relationship indication information, and determines target spatial relationship information of the target SSB, so that the terminal device determines the target spatial relationship information as spatial relationship information of the uplink channel/signal. That is, the target spatial relationship information is used to determine the spatial characteristics of the transmission of the uplink channel/signal, so that the terminal device transmits the uplink channel/signal according to the spatial characteristics determined by the spatial relationship information.

For example, when the network device indicates that there is a spatial relationship between the PUCCH and the target SSB through the spatial relationship, the terminal device determines that the spatial relationship information corresponding to the target SSB is the same as the PUCCH, and the terminal device may transmit the PUCCH using the same spatial domain filter as that used to receive the target SSB.
